如何在一个媒体查询中定位iPhone 3GS和iPhone 4？ [英] How to target iPhone 3GS AND iPhone 4 in one media query?

问题描述

我已经确定最好的方法是使用 @media 从CSS3规格。

因此，这是我的媒体查询时间：

  @media screen and（max-width：1000px）{...} 
  

以上是适用于小型桌面和笔记本电脑屏幕。

  @media max-width：700px）{...} 
  

笔记本电脑屏幕。

  @media屏幕和（max-device-width：480px）{...} 
  

以上内容适用于iPhone 3GS和移动设备。

然而，新的iPhone 4与史蒂夫·乔布斯的所有唱歌全跳舞视网膜显示器意味着它的像素比为2-1意味着1像素实际上显示为浏览器2x2像素的分辨率（960x640 - 意味着将触发iPad布局而不是移动设备布局），因此这需要另一个媒体查询（目前只有webkit支持）：

  @media screen and（-webkit-min-device-pixel-ratio：2）{...} 
  

现在，事情是...我想要我的漂亮闪亮的新iPhone 4布局合并与iPhone 3GS和移动设备布局，因为他们都有完全相同的内部CSS代码，

因此提出我的问题;

如何创建 @media

解决方案

因为iPhone和iPod触摸测量 max-device-width 在逻辑像素而不是物理像素，即使与视网膜显示器（因为他们应该），用于iPhone的原始媒体查询应该足够：

  @media only screen and（max-device-width：480px）{
 / * iPhone CSS rules here * / 
} 
  

您只需要 min-device-pixel-ratio：2）如果您需要分别定位Retina显示。

I am trying to implement alternate layouts for both the iPad/iPhone and older iPhones as well.

I have established that the best method is to use @media from the CSS3 spec.

As such these are my media queries at the minute:

@media screen and (max-width: 1000px) { ... }

Above is for small desktop and laptop screens.

@media screen and (max-width: 700px) { ... }

Above is for the iPad and VERY small desktop/laptop screens.

@media screen and (max-device-width: 480px) { ... }

Above is for iPhone 3GS- and mobile devices in general.

However, the new iPhone 4 with Steve Jobs's all-singing all-dancing "retina" display means that it has a pixel ratio of 2-1 meaning 1 pixel actually appears to the browser as 2x2 pixels making its resolution (960x640 - meaning it will trigger the iPad layout rather than the mobile device layout) so this requires ANOTHER media query (only so far supported by webkit):

@media screen and (-webkit-min-device-pixel-ratio: 2) { ... }

Now, the thing is... I want my nice shiny new iPhone 4 layout amalgamated with the iPhone 3GS and mobile device layout as they will both have exactly the same inner CSS code,

Therefore making my question;

How do I create an @media rule that points both the iPhone 4, 3GS and other mobiles to the same styles?

解决方案

Because the iPhone and iPod touch measure max-device-width in logical pixels rather than physical pixels even with the Retina display (as they should), the original media query used for the iPhone should be enough:

@media only screen and (max-device-width: 480px) {
    /* iPhone CSS rules here */
}

You'll only need (-webkit-min-device-pixel-ratio: 2) if you need to target the Retina display separately.
